Is it normal for me to be able to move my testicles voluntarily? By shifting a muscle in my stomach, I can lift them about 2 inches. Should I be worried or embrace my new talent?:)

Oh what fun we have playing with ourselves, and just think you would not have learned this little trick if you had done what you had heard all you live and not played with yourself. Oh by the way you are not the only guy that can do that so if somehow it make you feel better to embrace your new talent then go right ahead.

No, you are not unique.

Were you to find a way to profit from this, you might be unique. Entrepreneurial, at the least.
